Random Sampling Case Studies

The educational change I will analyze is the Ten School Program this program was implemented in The Los Angeles Unified School District. According to LAUSD.net (2008) the one of main reason this program was to provide an instructional program and an organizational design and provide a language intensive that will redirect the pattern of poor academic achievement of African American and other students in predominately Hispanic, Black, Asian and other Non-Anglo (PHBAO) Schools also knowns as low income areas. According to the Los Angeles Unified School district "The focus for the ten school program is to demonstrate that all children can achieve their highest potential when the conditions for learning are at high standards starting with students attendance. Improve the academic achievement of TSP students in reading, math and language art, Lausd.net,(2008)". Below I will list the programs list of guidelines:

The community surrounding the school is very diverse, consequently, the school’s roll is made up of children from different ethnicities, with different social backgrounds.

information needed, random sampling was used based on 60 government agencies official Twitter accounts. In addition, during the course of 6 months, January to June 2010, researchers randomly collected 30 tweets to assess. The results were interesting and it ranged from the highest being 158 tweets to a low of 41 tweets. Waters also examined the “Frequency of government agencies’ tweets by the four model of public relations,” (Waters 358) which are press agentry, public information, two-way asymmetry and, two-way symmetry. This section of the research showed that 20.7% of people would mention someone else in a tweet without engaging in a conversation, which was two-way symmetry. While on Twitter, 1.5% of the users would express their emotions through emoticons, which was press agentry. Interestingly, in the research that Waters conducted he notes that in many cases, Facebook is used as a platform for organizations to share multimedia files and share information rather than engaging with the audience.

Statistical data analysis was performed using programs MATLAB R2012b or R2014a and was conducted at 95% confidence level. Amino acids in the hair protein were determined using the relative peak areas and the concentrations were determined from a calibration curve from liquid injections of standard amino acid solutions of GC/MS analysis [8]. Also, ANOVA (one-way analysis of variance) was used to compare the mean concentrations of each amino acid between the case-control study groups. The F-test that is used in ANOVA is used to determine the variability between group means is larger than the variability within groups. It can be concluded that not all the means are equal if the ratio is very large [5]. Rashaid et al. detected 4 amino acids

Everyone mentions simple random sampling, but few use this method for population-based surveys. Rapid surveys are no exception, since they too use a more complex sampling scheme. So why should we be concerned with simple random sampling? The main reason is to learn the theory of sampling. Simple random sampling is the basic selection process of sampling and is easiest to understand. If everyone in a population could be included in a survey, the analysis featured in this book would be very simple. The average value for equal interval and binomial variables, respectively, could easily be derived using

One of the greatest concerns with public schools is that the numbers are far too large, parents fear their child will get lost or overlooked. However, there are several benefits to placing children in larger communities with many different types of people. A study done in 1997 by the National Center for Education Statistics showed that “Racial and ethnic diversity can enrich the school experiences of students” (Findings from the Condition of Education 1997, p. 9).

Adam was an extraordinary kid. He feared nothing. When he was two, he jumped 12 feet from the deck at his house (pg 13). He played football, had amazing family and friends, and had his fair share of trouble. He always was kind to everyone and stood up for the underdog (pg 25). All of his classmates and teachers adored him. The worst mistake of his life started the first time he tried drugs (pg 44). This started a whirlwind of pain and anxiety on all of Adam’s family. Adam would disappear for long periods of time, steal from his parents, and had many bad influences (pg 48). He hit the lowest of the low while at a party when he stabbed himself in the neck (pg 55). This was very hard for everyone that knew Adam. He got sent to a rehab facility and faced many challenges while he was there (pg 57). He finally got released out into the real world after finishing the 12 step AA program (pg 58). Adam had many ups and downs after this.

This unit was designed for a regularly leveled ninth grade classroom with a wide variety of learning needs. The class is comprised of 18 boys and 12 girls with 30 students total. The students generally enter freshman year around the age of fourteen or fifteen. The school is located in a rural area in Northern Illinois. About 74 percent of the students are white, although the school has become much more racially diverse in recent years. The Hispanic population is the largest minority population present at about 12 percent, followed by 6 percent Asian, 4.5 two or more races and 2 percent black. Despite increasing minority populations only one percent of the student body are English Language Learners. Approximately 13 percent of the student

At Carthage High School there are two very distinct categories that students are a part of: “Hispanic” and “everyone else”. Over the past decade the school district has seen a dramatic increase in the number of Hispanic students that are being enrolled in our district. There have been numerous attempts to help meet the needs of our Hispanic students, most of them are English Language Learners (ELL), and while there has been progress made, there is much more that our school could be doing for these students. Data from state test results and annual yearly reporting (AYP) show our minority students are making progress but still fall significantly behind the non-ELL peers. Teachers are the key to seeing our Hispanic students achieve higher rates of success because they have the largest effect on the daily motivation and learning of these students in the classroom. Using interviews, observations, and artifacts produced by students my action research plan will show successful methods being used in the classroom and which methods are not helping to achieve the desired results for our students. My action research plan will also help bring to light the social issues that are being dealt with in our school and building as a direct result of the influx of diversity in our community and school. Our school is trying to aid in this area by introducing programs aimed at helping bridge the gap between the diverse cultures in our community. These programs will be reviewed to see if

When data randomization is applied without using random mask generation method, the results are predictable and having high performance overhead. On the other hand, when the results are interpreted using linear congruential method then it reduces the probability of attack because of unpredictable values and less performance overhead.

Data will also be collected from surveys given to parents and teachers regarding students. Surveys will be administered at the beginning of the school year before the program starts and again in the end of the year when the program has ended. Human subjects will be protected because parents and teachers will be asked to complete all surveys anonymously placing no names on surveys.

The sample must be representative of the population from which it is drawn and must have a good size to warrant statistical analysis. For the purpose of this study; (a) one (1) educator; (b) one (1) learner; (c) one parent; and (d) one (1) member of SGB will be randomly selected from 5 schools. This will provide the researcher with a sample of 20 participants.

Under the Pretest-Posttest with a control group design, the sampling technique to execute would be timeslots, with randomizations. Since last semester, the department use two sections in which integrated the revamped 6200 course and two section with the original design. Through the process of using timeslots, this assessment will allow participants to choose four different time slots that best suits their schedule for the semester. No participants will know which class is which, it will just be two sections of the course, four different time slots. Two classes will be the revamped course, the other two will be the traditional course. By using this type of design, this can eliminate selection bias. Once participants have begun their course, a pretest will be administered that test participants knowledge of public-sector administration, ethical protocol, execution all mutually related to being successful in public governance. Then at the end of the semester a post-test assessment would be given to test the participant’s knowledge. By utilizing this design, researchers are allowed to compare and contrast the final posttest results between the two groups, analyzing the overall effectiveness of this assessment. In addition, can determine from the results the researchers can see what changes occurs in the pretest and posttest, whether the case study group, or both the case study and traditional group , or neither improved over the semester or remain in the same

The observer may participate in the activities of the group being studied (participant observation) or he may just be a bystander (nonparticipant observation). When an observation is done in a laboratory, as in the case of experimental studies, the type of observation is called controlled observation.
